Definitions
- the term heat exchanger is any device for exchanging heat with an external element.
- the first pipe may be provided with a heater, a fan, or cooling fins, or have a shape conducive to heat dissipation.
- the heat exchanger is configured so that the temperature of the fluid leaving the first pipe is lower than the temperature of the fluid leaving the second pipe.
- the fluid passing in the first pipe enters the passive pumping member at a temperature different from the temperature of the fluid passing through the second pipe.
- the mixing between fluids at different temperatures within the passive pumping member allows the thermal regulation of the PAC.
- the thermal control system further includes a pump placed on the first conduit.
- the pump makes it possible to increase the pressure in the first pipe, that is to say to increase the pressure of the driving fluid before entering the passive pumping member, thus increasing the efficiency of the pumping member.
- passive Preferably, in order to limit the thermal load of the pump, the first pipe is used to circulate a cooler fluid than the second pipe.
- the pump is located between the heat exchanger and the passive pumping member.
- the electronic control unit 26 here has the hardware architecture of a computer. It may comprise in particular a processor, a read-only memory, a random access memory, a non-volatile memory and means of communication with the measuring device 30 enabling the electronic control unit 26 to obtain the measurements made by the measurement device. 30.
- the electronic control unit 26 and the measuring device 30 are for example connected by a data bus digital or a serial interface (eg USB (Universal Serial Bus)) or wireless interface known per se.
- the flow rate of the pump 28 is an intermediate variable. It is possible to indirectly control this variable by controlling control variables of the pump 28 such as, for example, speed, voltage or current.
- control variables of the pump 28 such as, for example, speed, voltage or current.
- the different ways of controlling a pump are known per se and will not be described here.
- thermal control system suitable for a fuel cell
- said system can be used to thermally regulate other devices or devices whose temperature is adjusted by means of a heat transfer fluid.
